Methods and systems for synchronizing data may enable a computer to synchronize data by connecting to a peer computer via a network connection. The computer may receive a remote table from the peer computer, wherein the remote table comprises an object comprising a vector. The computer may determine whether the object is present in a local table. When the object is present in the local table, the computer may determine whether the vector in the remote table and the vector in the local table match. When the vectors do not match, the computer may determine whether a record of a change to the object is present in a local transaction log. The computer may receive data from the peer computer indicating whether a record of a change to the object is present in a remote transaction log when the vectors do not match. The computer may replace the vector in the local table with the vector in the remote table and record a change to the object in the local transaction log when the record of the change to the object in the local transaction log is less recent than the record of the change to the object in the remote transaction log.

Data replicating systems and data replicating methods

A network may comprise a plurality of nodes wherein each of the plurality of nodes is associated with one of a plurality of hives. A computer may connect to the network by establishing node data for each of the plurality of nodes, the node data indicating a hive with which the node is associated and including a flag indicating whether a connection attempt associated with the node is or has been unsuccessful. When a connection attempt is successful, the computer may determine whether the node to which the computer is connected is a preferred node associated with the preferred hive based on the node data. The computer may connect to the preferred node associated with the preferred hive when the node to which the computer is connected is not the preferred node associated with the preferred hive and the preferred node associated with the preferred hive is not marked unsuccessful.

Data replicating systems and data replication methods

A secondary containment piping system is composed of a plurality of modules of concentric pipe. The inner pipe carries fluid being transported, and the outer pipe provides secondary containment of fluid leaking from the inner pipe. The module consists of a length of inner pipe centred in a length of outer pipe by a series of spiders or ribs, fastened to one or both of the pipes. The ends of both inner and outer pipes are coplanar and perpendicular to the axis of the module. Successive modules are joined by simultaneously welding the inner and outer pipes of one module to the corresponding pipes of an adjacent module, the preferred material for the pipes is HDPE and the welding is accomplished using electric fusion welding techniques.

Secondary containment system

The power chuck of the invention features a series of rocker arms which are linked by toggles to the chuck's actuator. The rocker arms are mounted on pivot pins which pivot with respect to carriers within the body of the chuck. The center of gravity of the toggle, rocker arm and jaw mounted on the end of the rocker arm is located inwardly of the pivot pin so to provide increasing clamping force as the rotational speed of the chuck increases. A spring within the carrier provides a pull-back action on the workpiece during clamping.

Power chuck

An inner diameter chuck which has a cup shaped holder with a concave face joined by the interior side of the face to a base portion. The holder will flex upon movement of an actuator against the lip of the cup to change the outer diameter along the forward side portions of the cup so to allow for engagement and disengagement of a workpiece.
